IMPROVEMENT lN COOLING APPARATUS FOR STAND-PIPES 0F GAS-RETORTS.

Specification forming part of Letters Patent N 0. 192,944, dated July 10, 1877; application filed April 23, 1877.

To all whom it may concern:

Be it known, that 1, DAVID R. SHIRAS, of Sharon, in the county of Mercer and State of Pennsylvania, have invented a new and Improved Oooling Apparatus for the Stand-Pipes of Gas-Retorts, of which the following is a specification:

Figure 1 is a side elevation of my improved apparatus. Fig. 2 is a plan view of the same.

Fig. 3 is aplan view of a series of stand-pipes,

to heat the retort s to the maximum temperature without causing a stoppage in the standpipes, and thereby increase the production of gas, as well as improving its quality and greatly diminishing the time occupied distilling the charge. I

Referring to the drawing A is the ordinary stand-pipe, which conducts the gas from the mouth of the retort to the hydraulic main; and B is a curvedpipe surrounding the same, which is perforated from'the under side, so as to direct a number of jets of water against the stand-pipe.

This curved pipe is made in two sections, which are connected together 'by a union, a; and it is connected with a water-supply pipe by a union, 1), and a short section of lead or other flexible pipe.

Wherea series of stand-pipes are employed the curved-pipes are arranged as shown in Fig. 3, one-half, B, of the curved pipe of each of the adjacent stand-pipes being connected to a central supply-pipe, c, which is connected with a main pipe, d, that supplies the series with water.

The ends of the curved pipes are provided with openings closed with plugs e, which may be removed when the pipes need cleaning.

A stop-cock, f, is placed in each of the supply-pipes c, for controlling the flow of water.

An annular-trough or channel, 0, surrounds the lower end of the stand-pipe A for receiving the water discharged by the perforated pipe B against the surface of the stand-pipe. A pipe is connected with the trough O for conducting away the water. This trough may be formed on the stand-pipes when they are cast; but when the improvement is applied to works already completed a sectional trough or channel, 0, (shown in Fig. 4) may be placed around the lower end of the stand-pipe and secured together by bolts, the joint between the said trough or channel and the stand-pipe being made water-tight by'means of any suitable cement.

When it is required to remove the standpipes the curved pipes B may be readily removed by disconnecting the unions b.

The advantages secured by my improvement are the avoidance of clogging in the stand-pipes, the more economical production of gas, and the saving of time in its manufacture.

Having thus described my invention, I claim as new and desire to secure by Letters Patcut-- The curved perforated pipe B, in combination with the stand-pipe A, and annular trough G, as and for the purpose specified.

DAVID R. SHIRAS.
